1 NETWORK INTERFACE CABLE NETWORK INTERFACE MODULE INSTALLATION FEATURE NUMBERS 000-F-0xx, 00-F-xx, 00-F-0x Installation Instructions Document Number 000-A-GZ-0 December 999 OVERVIEW This document describes the installation of digital, analog leased-line, dial network, and Switched kbps digital service interface cables used by the COMSPHERE 000 Series Carrier. The installation of Network Interface Modules, required for any dial-line or Switched kbps digital service interface, is also described. NETWORK INTERFACE MODULES The COMSPHERE 000 Series Carrier has a total of slots. The first slot, Slot 0, is reserved for the Shared Diagnostic Unit (SDU). The remaining slots can house up to Data Service Units (DSUs) or dial/leased modems or a mixture of both. The digital, analog leased-line, or dial network interface for these units is provided through 0-pin connectors located on the rear of the carrier. The carrier is divided into two halves, Slots through and Slots 9 through. If devices installed in Slots through are DSUs and/or leased-line modems, then the network interface uses the 0-pin plug-type connector labeled P. Likewise, for Slots 9 through, the network interface uses the 0-pin plug-type connector labeled P. However, if any device installed in Slots through or Slots 9 through is a dial modem and/or a DSU with a V. or Switched Dial Backup Module (DBM), then a Network Interface Module (NIM) must be installed. The NIM for Slots through attaches to connectors P and P. Likewise, if dial modems or DBMs are installed in Slots 9 through, the NIM attaches to connectors P and P. There are a total of nine different NIMs (see Table ). One NIM, feature number 000-F-0, is used for the DSU with -wire Switched DBM (SJA); another NIM, feature number 000-F-00, is used for the V. DBM (RJX) or the -wire Switched DBM. The remaining NIMs are either programmable (RJX) or permissive (RJX). Programmable NIMs correct any loss in the transmit signal level between the modem and the central office by permitting the modem to transmit at the optimum signal level. This is accomplished by the local telephone company installing a resistor into the network interface demarc and is identified by an RJS-type jack for single-line equipment or an RJX-type for multiline equipment. Permissive NIMs used for standard dial-line connections are identified by RJC-type jacks. Additional features available for both programmable and permissive NIMs are Service Line and Make Busy. The Service Line feature permits an extra dial line to be connected to a COMSPHERE 000 Series Carrier. NIMs with this feature are identified by the two modular connectors mounted on the NIM. Permissive NIMs are also used for -wire Switched kbps connections. 000-A-GZ-0 December 999

2 The Make Busy Feature ties the and signals together through a resistor so that the modem appears busy to the PBX. WARNING To not violate FCC and DOC regulations, a NIM with the Make Busy feature must only be used behind a user s PBX. Make Busy is not used by DSUs with DBMs installed and will not affect the DBMs performance. However, if a DBM or a dial or APL modem uses a NIM with this feature, it must be used behind a PBX. Table shows NIMs available for dial-line and Switched kbps networks.

4 NETWORK INTERFACE CABLES Network interface cables connect the carrier to the digital, analog leased-line, dial, or Switched kbps network interface demarc. Two basic types of cables are used: a plug-to-socket 0-pin mass termination cable and a 0-pin modular plug conversion cable. A 0-pin mass termination cable (see Table ) can be used to extend the distance between the carrier and the demarc or can be used if the network interface to the carrier is via a A-punchdown block. This cable has 0-pin connectors at each end. The socket-type connector attaches to the rear of the carrier and the plug-type connector attaches to either a A-punchdown block or a 0-pin to modular plug conversion cable. Table 0-Pin Mass Termination Cables FEATURE NUMBER 00-F-0 00-F-0 00-F-0 DESCRIPTION 0 ft., plug-to-socket 0-pin mass termination cable (can be used as an extension for 0-pin to modular plug conversion cable). 0 ft., plug-to-socket 0-pin mass termination cable (can be used as an extension for 0-pin to modular plug conversion cable). 00 ft., plug-to-socket 0-pin mass termination cable (can be used as an extension for 0-pin to modular plug conversion cable). In environments where modular-type interface wiring is used instead of a punchdown block, a 0-pin to modular plug conversion cable is used. This cable has one socket-type 0-pin connector (attaches to the rear of the carrier) that branches out to eight modular plugs (see Figure ). Each modular plug is labeled through to correspond with device locations in Slots through or Slots 9 through. 9-a-0 Figure. 0-pin to Modular Plug Conversion Cable December A-GZ-0

11 DIGITAL, ANALOG LEASED-LINE, OR SWITCHED KBPS NETWORK INTERFACE CABLE INSTALLATION Two 0-pin connectors (P and P) provide the carrier s digital and analog leased-line network interface. Connector P serves Slots through and connector P serves Slots 9 through (Figure ). Refer to Table to determine if your network interface cable is compatible with DSUs and leased-line modems residing in the same half of the carrier. Preform the following procedures when connecting a network interface cable to the COMSPHERE 000 Series Carrier and appropriate demarc. Use Figure as a reference for connector locations. NOTE For digital and analog leased-line installation in Canada, a special network interface cable is provided (feature number 000-F-009). For installation of a -wire Switched kbps network connection, the cable provided is an SJA adapter cable (feature number 00-F-0). Follow the installation procedures listed below, only substituting the 000-F-009 interface cable or cable for the 0-pin to modular plug conversion cable described in Step.. Connect the 0-pin mass termination network interface cable s 0-pin socket to the 0-pin connector (labeled P) on the rear of the carrier for Slots through. If Slots 9 through are used, connect the 0-pin socket to connector P.. If a right-angle cable is used, secure the cable by attaching a cable tie to the cable near the hood at the carrier s cable-tie attachment point. If a straight-in cable is used, disconnect the cable-tie, remove the screw and cable-tie mount, and fasten the cable with two screws.. If the 0-pin mass termination cable is to be attached to a A-punchdown block, continue with Step. If the 0-pin mass termination cable is used as an extension cable, go to Step. Attach the plug end of the network interface cable to the A-punchdown block (the DSU and/or leased-line demarc). Installation of the 0-pin mass termination cable is completed.. Attach the plug end of the network interface cable to the socket connector on the 0-pin to modular plug conversion cable.. Attach the proper modular plug to the proper DSU or leased-line demarc. The modular plugs are labeled through and correspond to the devices in those slot positions in the carrier. For example, for Slots through, modular plug is wired for the device in Slot, modular plug is wired for the device in Slot, and so on. For Slots 9 through, modular plug is wired for the device in Slot 9, modular plug is wired for the device in Slot 0, and so on. This completes the digital, analog leased-line, or Switched kbps network interface cable installation. 000-A-GZ-0 December 999

Digital and Leased-Line Installation NETWORK MODULE INTERFACE INSTALLATION If a dial modem, an analog leased-line modem using dial backup, or a DSU with a DBM is installed in a COMSPHERE 000 Series Carrier, then a Network Interface Module (NIM) must be attached to the carrier s backplane. Prior to the NIM installation, verify whether your dial connection is programmable (RJX) or permissive (RJX). To install a NIM on the carrier s backplane, refer to Figure for connector locations and perform the following steps:. For Slots through, seat the NIM on connectors P and P located on the carrier s backplane. If Slots 9 through are used, attach the NIM to connectors P and P.. Use the four screws provided with the NIM to secure it to the carrier. This completes the NIM installation. December A-GZ-0

Refer to Table to determine if your cable is compatible with the NIMs used. To connect a network interface cable to the COMSPHERE 000 Series Carrier and appropriate demarc, refer to Figure for connector locations and perform the following steps:. For Slots through, connect the network interface cable s 0-pin socket connector to the 0-pin connector on the NIM located above connector P. If Slots 9 through are used, connect the 0-pin socket to the NIM located above P.. Use a small screwdriver to tighten the screws on each side of the cable connector. 000-A-GZ-0 December 999
